New Jersey regulators will hold a hearing Sept. 10 on an application by pipeline company Williams to build a natural gas pipeline across part of Lower New York Bay.

The Northeast Supply Enhancement Project is a proposal to upgrade Williams’ existing Transco pipeline network in part by adding a 23-mile section of underwater pipeline across Raritan Bay and New York Harbor, connecting New Jersey and New York.

The project is meant to deliver more gas from Pennsylvania to gas utility National Grid in New York and was originally authorized by the Federal Energy Regulatory Commission in 2019. It was expected to begin operating in 2021 but faced years of opposition and delays, with the company failing to secure key state-level water permits.

After allowing its authorization to expire last year, Williams revived the project in May under the Trump Administration with a new FERC application.

The company’s plans to build the underwater pipeline have faced opposition for risks to the endangered North Atlantic right whale and other marine species.

The New Jersey Department of Environmental Protection will hold a virtual public hearing on the proposal from 6-9 p.m. on Sept. 10. See the public notice for more information.
